Hey Everyone, I recently had the update problem with my Vista software but along with the update not working, my control panel wasn't working either and I kept getting and error message that I couldn't find in any Yahoo search then I found a post somewhere that told me to do this:

Go to Start, Run, Services.msc
Go to Software Licensing and either Start or Restart
Then go to SL UI Notification Services and Start

That's it, it fixed my update and control panel, hope this helps you, thanks
